Nova 1998 2 in M31 this image of the second Nova in M31 in 1998, was made from 38 exposures of 45 seconds integration time. It was made at September 21, 22h 20m UT. Telescope was a CG11 at f/6.3, no filters were used. The long list of processing steps caused the artefacts at the overexposed center of the galaxy and in many of the brighter stars. During the exposures thin clouds covered the sky but the CCD cuts through them, allowing me to obtain this result. ...

. Comment on J0126-0123 . No detection: this object has been studied with the Molonglo telescope at 408 MHz (Schilizzi & McAdam 1975) as a source with a size between 2 and 5 . It is near an Abell cluster (Owen & Ledlow 1997). The data could be confused with a strong radio source (3C 40) identified with a pair of galaxies at z=0.018, 170" from our field center.
